Crop Variety Testing And Recommendations, H M. Fisher

Journal of the Department of Agriculture, Western Australia, Series 4

From 1984 onwards, the Department of Agriculture's crop variety recommendations for Western Australia will be set out in a new format directly related to the 18 variety testing areas into which the South-West has been divided. These divisions should enable growers to more readily identify the recommendations which apply to their area. In addition, yield data on the varieties are provided for each area.

The recommendations are the culmination of a lenghty process of breeding, selection and testing of crop varieties. This article gives the background to the tests and how the results are used as the basis for the …

Barley Production And Soil Acidity, P J. Dolling, W. M. Porter

Journal of the Department of Agriculture, Western Australia, Series 4

One of the causes of reduced plant yields on acid soils is aluminium toxicity. because barley is extremely sensitive to this mineral, a project started last year to examine the influence of soil acidity on barley production in the main barley growing areas of Western Australia.

This article discusses some of the background information on the project and its aims.

Soil Acidity And Liming In The Lower Great Southern, R N. Glencross, M. G. Clarke

Journal of the Department of Agriculture, Western Australia, Series 4

In the 375 to 750 millimetre rainfall area of the Lower Great Southern, reports of loss of subterranean clover from established pastures, reduced carrying capacity for sheep and increasing soil acidity lead to the establishment in 1981 of a research programme into the effects of soil acidity on pasture productivity in that region.
